This has become one of my favorite campgrounds. What we have learned is that if you will go online and make a reservation (loop B), you can move your reservation to one of the non-reservable loops (A or C) once you get there. So if you find a site on the river or one with more trees in the outer loops, the camp hosts will let you change your site number. I love this feature as it also helps us to avoid noisy neighbors or shadeless sites. The park in general has lots of interesting, educational, and/or scientific sites. Plenty to stay busy plus the added bonus of having a river to cool off in. We have AT&T and had enough 4G throughout the campground to stream a Broncos game with minimal interruptions.
